Is Your HVAC Leaking Money?
The average DMV home loses 25% of conditioned air through duct leaks — the equivalent of leaving a window open year-round. Aeroseal duct sealing permanently fixes it in one day, without opening a single wall.
7 Signs Your Ducts Are Leaking Energy
Duct leaks are invisible — but their symptoms are not. If any of these sound familiar, you are almost certainly losing money every month.
Uneven Room Temperatures
Some rooms are perpetually too hot or cold despite thermostat adjustments.
High Energy Bills
Your cooling and heating costs are above average for your home size.
Dusty Rooms After Cleaning
Dust reappears quickly because leaky ducts pull unconditioned attic or crawl-space air inside.
HVAC Running Constantly
Your system never seems to reach the set temperature and runs non-stop.
Poor Indoor Air Quality
Allergy symptoms or musty odors suggest outdoor contaminants entering through duct gaps.
Visible Duct Damage
You can see disconnected joints, holes, or crushed flex duct in your attic or basement.
Home Built Before 2000
Older homes almost universally have unsealed duct systems with significant leakage.
Failed Energy Audit
A blower door test revealed high air leakage and your auditor recommended duct sealing.
5-Step Process. No Demolition. One Day.
Duct Leak Diagnostic
We pressurize your duct system and measure total leakage in CFM (cubic feet per minute) using a calibrated blower door. You receive a printed before-and-after report.
Vent Register Blocking
All supply and return registers are temporarily covered with foam blocks to contain the sealant aerosol inside the duct network.
Aerosol Injection
Our technician injects the UL-listed vinyl acetate polymer aerosol into the duct system under pressure. Particles suspended in air travel through the entire duct network.
Leak Site Bonding
Physics does the work — particles can only exit through gaps, where they accumulate, bond, and permanently seal holes up to 5/8 inch wide in 2–4 hours.
Final Verification & Report
We re-run the leakage test, confirm results, remove register blocks, and hand you a detailed digital report — including the exact percentage of leaks sealed. Most jobs achieve 90%+ sealing.
